The sphere as a metaphore is meant to be discussed in use in the body. No one really cares about wandering off into the weeds with more mechanical models that appear here that help no one-including those who draw them and have nothing unusual to show for there "understanding."

Uh, OK. So what is the metaphor of the sphere and what does it mean in relation to the body? I have never heard of this metaphor and have no idea what it refers to, and I'm probably not the only one. I have no way of knowing that there is a metaphor relating the body to a sphere unless someone says so...

My point in responding to the question about the sphere with a comment about different models of the sphere is that -- it depends what you mean by a sphere and it depends what you mean by stability. I.e., more info is needed to answer the question of whether a sphere is stable.

Personally I usually find mechanical models clear and metaphors just confusing unless I already know what the metaphor is talking about. So I often have no clue what people are talking about until they stop using metaphors and tell me directly what they mean. I have met people who were the opposite.
